Human Milk 4 Human Babies (HM4HB) is a global network, which is represented by community pages for states, provinces and countries.

The page itself posted the following today about 10am, likely on behalf of a member of the page.

"Hi, I have around 80ml of colostrum available in Mackay," the page wrote.

"Could you please see if any mums are in need? Couldn't donate to the hospital as they don't have a milk bank."

On the organisation's website the motivations behind sharing breast milk were explained:

"We want milk-sharing and wet-nursing to be commonplace and babies to be fed at women's breasts whenever and wherever they need it," it states.

"We envision a future where families come together to raise this generation, and the next, by nourishing human babies everywhere with human milk and unconditional love."

In another post seemingly shared on behalf of a member, the page described how one mum and her child had benefited from sharing breast milk.

"Looking to build our freezer supply of donor milk up again - we relied solely on donor milk since my son was born due to my uterus rupturing, the amount of blood loss and trauma caused my milk to not come in," the page wrote.

"I'm in the Bray Park area, willing to travel from Chermside through to Caboolture to collect milk. Can collect today or tomorrow - please message me or comment on the status."

The health benefits of breastfeeding are well documented.

The World Health Organisation recommends breastfeeding for the first six months of a child's life, with solids gradually being introduced.

It also advises supplemented breastfeeding until at least age two and then for as long as the mother and child wish.
